I drained and refilled 40% of my pool to reduce my extremely high CYA, alkalinity and chlorine. However, my CYA did not go down that I can tell! What is my next step?
NEW NUMBERS
FC = 9
CC = .4
PH 7.8
Calc = 210
TA = 325
CYA = 150 - 'Guesstimate' because black dot disappears so quickly.
I've learned so much about pool chemistry and the methods suggested here but I am frustrated the CYA didn't go down! Thank you for your suggestions!
